The Tapo camera can send you instant push notifications whenever movement, a person, or a crying baby is detected. It has night vision, two-way audio, and high-definition 1080p video. And at under $15, it's a budget-friendly way to keep an eye on your home.

My favorite device deal from Amazon's Big Spring sale is the all-new Blink Mini 2, which is on sale for only $19.99. This compact security camera features two-way audio and will alert your phone when motion is detected. The Blink 2 also includes a 1080p HD live view, a night view in color with a built-in spotlight, and a wider field of view.

Today marks the final day of the Amazon Big Spring Sale. And if you haven't stocked up on all the best spring deals yet, now is your last chance. For instance, Amazon's best-selling smart home devices happen to be sporting major discounts as we speak.
